I have a website, to which I get on average 250,000 visitors every month. I use no keywords. And I make good money from it
Don't fix what isn't broken, if it works why change! By the way well done and yes keywords do get a lot of hype but if they work for others, then good for them, for yourself keep doing what you're doing. All the best!
What's the site? Just curious why your site is doing so well without any keywords, how does anyone find it? Do you use social media to drive traffic?
It's great to hear you make a good money... But this is surprising without keywords; social networking networks are a terrific method to attract traffic, but I believe you need also employ keywords. Keywords assist the algorithm in determining the topic of a piece of content. What a webpage is about in the eyes of search engines. Your web page will outperform your competition on search engines if you do it correctly.
Well its very good what you do ,think on how you can monetize it better and how to increase your website traffic and you will be succesful in no time
If you have hyperlinks their anchor text is going to be keywords on your site. Also image descriptions/alt text serve as keywords on your site.
